The important details.

XLSX is loaded only for this tool. Archive expansion limits guard compressed files. Macros, remote links and formulas are not executed. Legacy XLS binaries are not supported.

A good question.

Can I import a formula cell?

Only a cached displayed value may be read; formulas are never evaluated. Verify the preview before export.
